To include the JS and SCSS into your new project, you can either include/import/require the whole base lima.scss and lima.js into the top of your projects local files, or you can include individual files if you only need certain elements:

// import whole base scss
@import 'node_modules/ecce-lima/assets/scss/lima';

// import individual scss sheet from Project Lima
@import 'node_modules/ecce-lima/assets/scss/base/alerts';
// import whole base js
import from 'node_modules/ecce-lima/assets/js/lima.js';

// import individual js sheet from Project Lima
import from 'node_modules/ecce-lima/assets/js/controller/accordions.js';
